Amazon product: AUKEY 10000mAh Power Bank, 18W USB-C Portable Charger with Power Delivery & Quick Charge 3.0 Battery Pack for iPhone X, Nintendo Switch and More
Works well. Has low current charge mode for headphones and small electronics though I haven’t used it yet. Shuts off when device is fully charged. It is the perfect dimensions to carry alongside modern phones. 10000 mAh is more than enough for everyday use and is not the awkward size and weight that the 20000 mAh ones are. Can charge faster with two inputs and has quick charge to charge your devices faster. Those are the pros. | Cons: no cables or storage/carry bag were included.
